Given a set of data to train from, predict the next round possibility (Two out of Three Possibility)

Please Read the requirement carefully. The requirement is, Given a set of data to train from, predict the next round result. For example: (data will have much more items within it, but for example lets keep it small and it will only contain either 1, 2 or 3, real data will also only contain 1, 2 or 3) data = [3, 1, 3, 2, 3, 1, 3, 2, 3, 3, 3, 3, 1, 3, 2, 3, 2, 1, 1, 2, 1, 3, 3] The script should read that set of Data and predict the next possible outcome: Actual result: 2 (This we don't know) (But for example I am providing the actual result) Prediction: {1, 2} {2,3} or {1, 3} <-- it should choose the best possibility from this set of 3 So it will be like: {2,3} (noticed how the actual result is in the prediction) Even if its wrong, append the actual result to data array and continue the process again data = [3, 1, 3, 2, 3, 1, 3, 2, 3, 3, 3, 3, 1, 3, 2, 3, 2, 1, 1, 2, 1, 3, 3, 2] (noticed the actual result is at the end now) Repeat prediction for the next round Run through example: data = [3, 1, 3, 2, 3, 1, 3, 2, 3, 3, 3, 3, 1, 3, 2, 3, 2, 1, 1, 2, 1, 3, 3] Prediction: {1, 3} (console input)What is the result: 2 comparing: Prediction did not contain 2 [login to view URL](2) data = [3, 1, 3, 2, 3, 1, 3, 2, 3, 3, 3, 3, 1, 3, 2, 3, 2, 1, 1, 2, 1, 3, 3, 2] (Prediction runs again) Prediction: {2, 1} (console input)What is the result: 1 comparing: Prediction did contain 1 [login to view URL](1) data = [3, 1, 3, 2, 3, 1, 3, 2, 3, 3, 3, 3, 1, 3, 2, 3, 2, 1, 1, 2, 1, 3, 3, 2, 1] This repeats until the script is stopped I would like this to have a 85%+ accuracy rate (timeItPredictedCorrectly / TotalRounds) If you think you can obtain 85-90% (I have test data under the File section) I will award and payout after testing it myself. Please bid on the pay, as that is what I will use.
